The AI turned my 44 messy Gmail filters into 16 that work better

He had added 44 Gmail filters over 5 years and they were not working well. With an AI skill that uses the Gmail MCP and a lot of email history to test against, the set was cut down to 16 filters that work better with fewer false positives. He wrote the process down as a skill afterward.

How it works

  1. Runs an AI skill connected to Gmail through the Gmail MCP
  2. It checks his 44 filters against his email history
  3. The filter set is cut down to 16 that work better
  4. He writes the process down as a reusable skill

Why it’s worth knowing

Most people never touch their Gmail filters again. His were tested against years of his own mail, cut from 44 to 16, and the cleanup itself was saved as a skill anyone can rerun.
